Henry's law constant for tce
Web1 jan. 2012 · As expected, the Henry’s law constant is strongly dependent on temperature. For example, the Henry’s constant for tetrachloroethylene increases by a factor of around 24 from 8 to 91 °C. Henry’s constants for trichloroethylene, chloroform, and 1,2-dichloroethane increase by 24-, 17-, and 30-fold from 8 to 93 °C, respectively. WebWe present Henry’s law constants for trichloroethylene (TCE) in water between 10 and 95 °C determined using a modification of the Equilibrium Partitioning in Closed System (EPICS) procedure and calculated from vapor pressure and measured aqueous solubility data obtained by a column generator technique.
